The LUXE experiment aims at studying high-field QED in electron-laser and photon-laser interactions, with the 16.5 GeV electron beam of the European XFEL and a laser beam with power of up to 350 TW. The experiment will measure the spectra of electrons, positrons and photons in expected ranges of $10^{-3}$ to $10^9$ per 1 Hz bunch crossing, depending on the laser power and focus. These...

The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose neutrino experiment designed to determine neutrino mass hierarchy and precisely measure oscillation parameters by detecting reactor neutrinos from nuclear power plants, observe supernova neutrinos, study the atmospheric, solar neutrinos and geo-neutrinos, and perform exotic searches. The experiment is designed to use the...

The axion is a hypothetical pseudo-Goldstone boson proposed to naturally resolve the strong CP problem, a long-standing mystery in the topological vacuum structure of quantum chromodynamics (QCD). In particular, the QCD axions with masses on the order of $\mu$eV to meV are a strong candidate for dark matter. The cavity haloscope is one of the most effective to search for dark matter axions in...

The 2020 visionary update of the European Strategy for Particle Physics endorsing the FCC feasibility study as a top priority for CERN and its international partners provides the HEP community with a powerful tool of investigations. As an essential and complementary step towards a 100 TeV hadron collider, the FCC will first feature an e+e- collider (FCC-ee). The very high luminosity, the...

The ATLAS experiment at CERN is constructing upgraded system for the "High Luminosity LHC", with collisions due to start in 2029. In order to deliver an order of magnitude more data than previous LHC runs, 14 TeV protons will collide with an instantaneous luminosity of up to 7.5 x 10e34 cm^-2s^-1, resulting in much higher pileup and data rates than the current experiment was designed to...

Belle II is considering upgrading SuperKEKB with a polarized electron beam. The introduction of beam polarization to the experiment would significantly expand the physics program of Belle II in the electroweak, dark , and lepton flavor universality sectors. For all of these future measurements a robust method of determining the average beam polarization is required to maximize the level of...

Flavor physics holds great potential to investigate fundamental aspects of the standard model such as mass hierarchy, electro weak symmetry breaking and more. Within this physics frontier, charged lepton flavor violation (CLFV) is a phenomenon that is highly suppressed in the standard model and an excellent probe of new physics. Current generation CLFV experiments like Mu2e, COMET, MEG and...

The COMET Experiment at J-PARC aims to search for the lepton-flavour violating process of muon to electron conversion in a muonic atom, $\mu^{-}N \rightarrow \mathrm{e}^{-}N$, with a 90% confidence level branching-ratio limit of $6\times 10^{โ17}$, in order to explore the parameter region predicted by most well-motivated theoretical models beyond the Standard Model. The need for this...

The Mu2e experiment is currently being assembled at Fermilab for its first beam in 2025. This experiment will search for the Standard Model violating neutrinoless conversion of a muon into an electron by detecting the delayed, essentially monoenergetic electron from a muon trapped in an Aluminum atom. The goal is to search for this signal at a rate approximately four orders of magnitude...

The Belle II experiment at the SuperKEKB e+e- collider has started data taking in 2019 with the perspective of collecting 50ab$^{-1}$ in the course of the next several years. The wealth of physics results obtained with the current data sample of about 400fb$^{-1}$ is showing that the detector is working well with very good performance, but the first years of running are also showing novel...

The COMET Phase-I and -II experiments will search for the muon-to-electron conversion process with a sensitivity improving the current upper limit on its branching ratio by a factor of 100 and 10000, respectively. An observation will be a splendid sign of the existence of physics beyond the standard model. The experiment utilises the world's highest-intense proton beam of J-PARC in Japan to...

The LHCb detector optimised its performance in Run 1 and 2 by stabilising the instantaneous luminosity during a fill. This is achieved by tuning the distance between the two colliding beams according to the measurement of instantaneous luminosity from hardware-based trigger counters. The upgraded LHCb detector operates at fivefold instantaneous luminosity compared to the previous runs, and it...

A precise measurement of the luminosity is a crucial input for many ATLAS physics analyses, and represents the leading uncertainty for W, Z and top cross-section measurements. The final ATLAS luminosity determination for the Run-2 13 TeV dataset is described, based on van der Meer scans during dedicated running periods each year to set the absolute scale, and an extrapolation to physics...

The increase of the particle flux (pile-up) at the HL-LHC with instantaneous luminosities up to L โ 7.5 ร 1034 cmโ2s โ1 will have a severe impact on the ATLAS detector reconstruction and trigger performance. The end-cap and forward region where the liquid Argon calorimeter has coarser granularity and the inner tracker has poorer momentum resolution will be particularly affected. A High...

After successfully completing Phase I upgrades during LHC Long Shutdown 2, the ATLAS detector is back in operation with several upgrades implemented. The most important and challenging upgrade is in the Muon Spectrometer, where the two inner forward muon stations have been replaced with the New Small Wheels (NSW) system featuring two entirely new detector technologies: small strip Thin Gap...

The LHC machine is planning an upgrade program which will smoothly bring the luminosity to about $5-7.5\times10^{34}$Hz cm$^{-2}$, to possibly reach an integrated luminosity of $3000-4000\;$fb$^{-1}$ over about a decade. This High Luminosity LHC scenario, HL-LHC, starting in 2029,
In order to fully exploit the delivered luminosity and to cope with the demanding operating conditions, the...

The success of the CMS physics program at the HL-LHC requires maintaining sufficiently low trigger thresholds to select processes at the electroweak scale. With an average expected 200 pileup interactions, critical to achieve this goal while maintaining manageable trigger rates is in the inclusion of tracking information in the Level-1 (L1) trigger. A 40 MHz silicon-based track trigger on the...
